In order to solve stope landslide prone problem in ion-type rare earth mines, a field experiment in a landslide prone region was conducted to find out the prevention and control measures. Through the establishment of water level monitoring system, waterproof and drainage system and field monitoring system, combining with manual inspection, critical injection strength, injection parameters optimization and artificial reinforcement strategy with strict control thiamine injection ceiling at 765 m 3/d and steel concrete grouting plus anti slide pile with steel wire connection of artificial reinforcement engineering, safety production of experiment stope and effective recovery of rare earth resources were obtained. The experiment proves that the research result and solutions to landside have strong practical significance and good economic-social benefits.
